apwsmb, did we build in i2c in lucid do you remember ?16:03
smbI would say so.16:04
smbAll the edid stuff at least uses i2c16:04
smbOh you mean built in or module?16:04
apwyeah i was wondering if it went to built-in16:05
smbHm, i2c_algo_bit at least is a module16:06
smbSeems CONFIG_I2C=y but the rest of the specific drivers is modules16:07

apwsmb, thanks .... yeah its just built so they should be able to use the kernel command line16:14
apwogasawara, i've just linked bug #589439 to the configuration blueprint.  seems to be a bunch of requests recommendations in there we should think about for maverick16:14

ogasawaraapw: indeed.  seems the spec still needs drafting so still no idea what our work items will entail16:21
apwogasawara, got a pointer to the spec there ?16:22

apwogasawara, thanks i'll go poke him16:22
robbiewmissing work items from doko, i believe16:23
apwogasawara, we arn't going to want to change the kernel config at that fundamental level after alpha-316:23
ogasawaraapw: agreed16:23
apwrobbiew, well if they don't sort out whats going to happen on that one before long we are going to have to punt on it16:23
apwwe can't be making that level of change after a316:24
apwand if they haven't changed the compilers yet, they are making all the archive rebuild tests moot16:24
apwnone of which sounds like a good thing (tm)16:24
robbiewapw: ack16:25
apwsmb, what time is the bug meeting ?16:32
smbapw, half an hour by my clock.16:33
smbNot that I had any time to prepare for anything16:33
apwsmb, i know i am punching self in the face as it is16:34
smbapw, Well likely go there and make smug comments without being prepared. :-P16:35
dokoapw, ogasawara: ping16:37
dokodo you use explicit cpu flags for kernel builds?16:38
apwdoko, yes we completely override all compiler flags16:38
apwthat is the nature of the builds, as we build 3-4 different flavours16:38
dokoapw: but you already did drop the i386 build, did you?16:39
apwdoko, yes we already dropped the explicit i386 builds16:39
apwbut our generci builds are hovering around the 586 level16:39
dokoapw: and how is the default build on i386 built?16:39
dokoapw: why i586?16:40
apwcause that is what lucid supported and its not be changed to match your documentation on where we are going, as its not yet documented16:40
apwthe only info i have seen was scotts announcement at uds ... "we are going move up to M686 + CMOV" but ... i've no idea if thats been done16:41
dokoapw: hmm, did we do document i586 as supported? the default was i486 in lucid16:41
dokoapw: it's in the archive since uds16:41
apwdoko, right in userspace that is correct.  if you wanted to use i486 you had to use the i386 flavours ... which were actually i486 minimum16:41
apwthe generci ones are a middle m586, ie m586 + some specific features16:42
dokothere is one guy who is keen on geode lx support16:42
apwdoko, ok ... meaning?16:43
apwdoko, i guess this is the discussion that we need to get written down in the spec, so that we can make an informed decision16:44
dokoapw: that you should not pass -Wa,-mtune=i686 to the assembler16:44
apwdoko, so have we changed the compiler flags to do that generally ?16:45
dokoapw: no16:45
dokobut some packages do pass this *explicitely*, and if you pass everything explicitely ... and no, not known when discussing this spec, just later when a user complained16:46

smbHm, I think I got an old stick18:27
apwsmb, any chance you could shove it in something with a maverick kernel on it ?18:28
smbNot that I currently have any Maverick on anything yet18:28
smbBut I likely need to set up some installations anyway18:28
apwsmb, i only have the lts-backports kerenl installed that would do as this is slated to be kernel issue18:28
smbapw, I'd rather have it tried on a separate installation. Might do one tomorrow if that is soon enough18:29
apwsmb, yep thanks18:29
bjfapw, i just tried the oldest stick I have and it worked, i have to believe it's 1.018:31

apwthe tester i have problems with has usb1.1 devices ... old memory stick and a using ohci as interface18:45
apwlooks like the only combination affected18:45
smbapw, But that could be ohci from a usb 2.0 hub (the companion hub) or a real usb 1.0 only hub, couldn't it?18:46
apwsmb, yes it could no way to tell, the only info i have is they have ohci18:46

squarebracketwhy wasn't the wacom kernel module included in the latest kernel update? (for lucid)20:21
tgardnersquarebracket, there are 3 wacom modules. which one do you think is missing?20:23
tgardnerinput/tablet/wacom.ko, input/touchscreen/wacom_w8001.ko, hid/hid-wacom.ko20:23
squarebracketthe first one.20:23
squarebracketsearching for wacom.ko at packages.ubuntu.com it doesn't look like it's included in the latest kernel20:24
tgardnersquarebracket, find /lib/modules/`uname -r` -name wacom.ko20:24
tgardner/lib/modules/2.6.32-24-generic/kernel/drivers/input/tablet/wacom.ko20:25
squarebracketyeah, i haven't done that yet... i compiled my own kernel module from the linuxwacom source but i'm looking into why my friend's tablet isn't working, and he didn't have the kernel module loaded; i assumed it was a missing kernel module20:26
tgardnersquarebracket, maybe its a new and unsupported device20:26
squarebracketi've written a batch script to look for it, if not compile it from source... but he's at work right now20:26
squarebracketit's not20:26
squarebracketit worked before the kernel update20:26
squarebracket(which is -23 i think)20:26
tgardnersquarebracket, he's running the -proposed kernel, right?20:27
squarebrackethe's running just vanilla ubuntu, i figured it would be -generic?20:27
tgardnersquarebracket, no, I meant which pocket is he subscribed to, e.g., -updates or -proposed. 20:28
squarebracketoh! that's a good question, i'm not sure.20:29
squarebracketshould be whatever defaults20:29
tgardnersquarebracket, get him to run 'ubuntu-bug linux' so we get the pertinent details.20:29
squarebracketsure, will do, i'll throw it into the bash script and pipe it to a file.20:30
tgardnersquarebracket, uh, you only need to run it once, preferably using the kernel version that fails to load the tablet driver.20:30
squarebrackettgardner, yeah, it's a bash script to just check for wacom.ko / load one i compiled / compile if that doesn't work. it'll only run once.20:32
squarebrackettgardner, but considering there was no wacom.ko loaded when i did an lsmod, and wacom.ko isn't in linux-image-generic, i figured it was a missing module.20:32
squarebracketi'll file a bug in launchpad once i know for sure what the problem is. thanks for your help!20:34

sconklinapw_: ok. It looks like the message I had never seem before is something seen in other places when git garbage collection is triggered during a push, and is harmless20:53
sconklinbut I was unable to fetch one of rtg's trees as a remote but was able to clone it outright20:53
tgardnersconklin, yeah, I had it happen to me today as well. its a newer git that is causing it20:53

sconklinbut I think they are OK20:54
apwi wonder what thats the start of ... remove perhaps20:55
tgardnersconklin, thats exactly what I got. don't make a lot of sense, does it?20:55
apwi bet it is the first four chars of something longer ... but git is not meant to do that20:55
apwits meant to negociate levels between the ends and dumb itself down20:55
apwsconklin, w20:55
sconklinno, and my brain kept trying to parse "sideband demultiplexer" in a radio context and failing20:55
apwwhat did you try to clone ... i'd like to as well20:56
apwsconklin, heh ... git protocol carries more than one channel ... so that you can get remote messages as well as the data you want20:56
apwthats how it does the percentages pulled down for example... its a bit like CD20:56
sconklinthe above errors came from a puch on the ubuntu-lucid master when garbage collection got triggered.20:56
sconklingit://kernel.ubuntu.com/rtg/ubuntu-lucid-lbm is the one I can clone but not fetch as a remote20:57
